Unbeknownst to their mother, Michelle and her stepbrother, James, find themselves in a tense situation. Bored and alone, they retreat to their respective rooms, only for Michelle to masturbate in the bathroom, her moans echoing through the house. James, overhearing, bursts in, catching Michelle in the act. They argue, but later, a truce is called. Naked, they mutually masturbate, Michelle's eyes locked on James' throbbing cock. Just as they're about to cross the line, their mother returns, halting their forbidden encounter.
